Abstract
A case for use with a propellant charge has a substantially cylindrical envelope. The envelope is formed from a combustible material. At least one support, that is formed from a combustible material, is coated to a substantially uniform thickness on at least one reception section with an anti-wear additive. A mechanism, formed from a combustible material, positions the support relative to the envelope such that, after assembly, at least one empty space is defined between an inner surface of the envelope and the anti-wear additive.
